What was the name of the expedition led by Meriwether Lewis and William Clark?

The expedition led by Meriwether Lewis and William Clark is known as the Corps of Discovery. This mission was part of President Thomas Jefferson's initiative to explore the newly acquired territory following the Louisiana Purchase in 1803. The Corps of Discovery set out in 1804 with the objectives of mapping the area, establishing trade with Native American tribes, and identifying a water route to the Pacific Ocean.

The significance of this expedition lies in its contributions to our understanding of the geography, biology, and cultures of the West. The detailed journals kept by Lewis and Clark provided invaluable information and insights that shaped future exploration and settlement in the region. The success of the Corps of Discovery helped to pave the way for westward expansion and laid the groundwork for the United States' understanding of its vast territories.

Other options, while they evoke imagery related to exploration, do not represent the official designation of the Lewis and Clark expedition and do not carry the same historical significance. The specific title "Corps of Discovery" is steeped in the legacy of their journey and its impact on American history.
